This is a black BabyBjorn One Kai Air. I believe it's in good condition with no noticeable stains, but there may be minor scratches and some pilling. It does show some signs of use compared to a brand new one. Please check the photos. If you have any concerns, I can add more photos, so please comment. It's mesh, so it's easy to wash and dries quickly, even if your baby sweats. It can be used all year round, but I think it's especially convenient for the coming season. It's black, so it's easy for both parents to use and matches well with clothes. Because it's mesh, it's easy to wipe clean and stains are less likely to remain. This baby carrier can be used from newborns to toddlers, so it will be a great help when you go out or do housework. You can put your baby in and out without taking off your outer wear, just using the front buckle, which is very convenient. It has been washed with baby detergent before listing. Please understand that this is a used item. [Product] Brand...BABYBJORN BabyBjorn Model... Popular model/series...BabyBjorn Baby Carrier ONE KAI Air (Mesh) Color... Black Pattern/Design...
